無法部署到 Graph 節點：註冊商不支持乙太坊網路：主網

我在圖形文件上遵循了本教程：https ://thegraph.com/docs/quick-start#local-development

但是，我在執行後收到一條錯誤消息yarn deploy-local。

Failed to deploy to Graph node http://127.0.0.1:8020/: Ethereum network not supported by registrar: mainnet

我在這裡有什麼遺漏嗎？

這是整個日誌

錯誤消息“註冊商不支持乙太坊網路：主網”可能會產生誤導，至少在我的情況下是這樣。我收到此錯誤是因為我已經hardhat node在主機上執行，但不是在主機上執行--hostname 0.0.0.0，並且我認為同樣適用於ganache-cli.

由於graph-nodeDocker 容器被配置為在 Docker 內部網路上查找以主機 IP 地址命名的乙太坊網路mainnet，因此它看不到hardhat node正在偵聽的127.0.0.1. 所以真正的錯誤不是不支持“主網”，而是無法訪問為“主網”配置的 IP 地址。跑步hardhat node --hostname 0.0.0.0成功了。

在本地執行圖形節點時， insubgraph.yaml的network值應該是mainnet，這在文件中並不清楚。

從這篇很棒的 dapp-development-with-a-local-subgraph文章中，

subgraph.yml 文件中定義的所有合約的網路必須是主網，即使您正在部署到本地節點。這不會與乙太坊主網路互動——這只是 subgraph.yml 需要為您的本地節點配置的方式。我學得很辛苦……
